The Hydraforce SV12-21-12T-N-12DS (5041817) is a solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge valve. This valve is specifically designed to function as a load-holding or blocking valve in systems that require low internal leakage. When de-energized, the SV12-21 allows flow from port 1 to port 2, while flow from port 2 to port 1 is significantly restricted. Upon energization, the valve's poppet closes against its seat, effectively blocking flow from port 1 to port 2 and acting as a check valve that permits flow from port 2 to port 1 once the solenoid force is overcome. Key features of this model include a continuous-duty rated coil and a hardened seat that ensures longevity and minimal leakage. The valve offers optional coil voltages and terminations for versatility in application. Its efficient wet-armature construction along with interchangeable voltage cartridges highlight its adaptable design. Additional attributes include a unitized, molded coil design and an optional manual override feature. For environments requiring robust durability, optional waterproof E-Coils are available rated up to IP69K. The SV12-21-12T-N-12DS operates within a fluid temperature range of -40°C to +120°C (with Buna N seals), demonstrating its capability in various operating environments. It supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. With maximum operating contamination levels specified per ISO standards, this model assures reliability even in demanding conditions. The valve is suitable for installation in VC10-3 cavity types without orientation restrictions, facilitating ease of integration into existing systems.
